Anchor for Tiled Wall

What would be the correct anchor to attach a sliding shower door (the weight is supported by the tub, the screws in the wall just hold it upright) to a tiled wall? The anchors that came with it look like they're for a thin acrylic tub surround. The wall is made of cement backer board with thick porcelain tile on it, probably about 3/4" to 1" thick total. Also, the H-shaped track has some distance between the screw hole and the wall (11/16"), I'm not sure if that has any effect on what to use. It's just that I searched and can't really find any place that says what anchors to use, so I want to make sure.

Cheap plastic anchors just tend to spin. If there's no backer for real screws you may want to concider using toggle bolts.
I agree 100 % with the other poster, I always use 2 X 6's at the edge of the tub so someone can install a curtain or a door.

mind you when i frame up for showers getting glass doors we put backing in where the door will go so we know the frame will be screwed to framing.

Sadly we didn't think of that at the time. I doubt that there's wood behind there.

My main concern about toggle bolts is that with the large hole, small screw, and the fact that there's some room between the wall and the screw hole, they might let the frame slide side to side a little against the tile. Is that a real issue?
